I use math when cooking or baking. If you have a recipe for 2 people, but you are making for 4 people, you will have to double the ingredients. So instead of 2 eggs its now 4 eggs. So for cooking, you will need to know bits of math for recipes so you don’t ruin the food or your taste buds. Also to convert Celsius to Fahrenheit or the other way around.
So math is vital to cook.
